Perhaps you should try some spelling variations:
"i largest decrease" » "i marked decrease" (Expand Search), "_ largest decrease" (Expand Search), "i large decrease" (Expand Search)
"ct values increased" » "ct cases increased" (Expand Search), "ct dalys increased" (Expand Search), "ct also increased" (Expand Search), "_ values increased" (Expand Search), "i values increased" (Expand Search)
"i larger decrease" » "i marked decrease" (Expand Search), "_ larger decrease" (Expand Search), "i large decrease" (Expand Search), "_ large decrease" (Expand Search)

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("i largest decrease") OR ("i larger decrease"))) OR ("ct values increased"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"i largest decrease\") OR (\"i larger decrease\"))) OR (\"ct values increased\"))".
• Removing quotes may allow a broader search: (((( i largest decrease ) OR ( i larger decrease ))) OR ( ct values increased )).
• Adding a wildcard symbol may retrieve word variants: (((("i largest decrease") OR ("i larger decrease"))) OR ("ct values increased"))*.
